DNS Zones 

2015 and still the best explination on DNS i've heard, thank you and keep them coming.

@20111in Glad you liked the video. Currently we don't have any jobs going.

No problem at all, thanks for watching.

@GMastrokostas Thanks, great to hear.

Thanks, glad you liked the video.

@mcitpstudent Thanks for the comment. More videos on the way.

Muito obrigado por compartilhar o conhecimento! Ótima iniciativa! thanks

Stub zones only forward requests for the zone that you create. A stub zone only has records in it which tells the DNS server where to forward requests to. They are generally used when you don't have access to the other DNS server. The stub allows you to enter in an IP address of the DNS server and forward all requests for that zone to that DNS server.

This is all true and the new video on DNS zones covers all this. This is quite an old video but it nice for you to give us the feedback.

Thanks. Glad to hear.

You should have a backup of all essential services in case the first one goes down. You can always remove and add Domain Controllers on your network as required.

I would check for file replication problems and DNS related replication problems. I would set your DC's to resolve DNS requests from themselves and the secondary the other DC. If you are having problems this can sometimes help fix things. Sometimes what the problem is that the DC cannot resolve certain object to perform replication. Changing the DNS server to the another DC other than itself helps the DC resolve better when they get out of sync.

In the DNS settings set correctly on the client? Is the zones available in the DNS server?

The primary zone that is created is created on anther DNS server that is not a Domain Controller. Before the zone is created a different DNS server is connected to. The admin tool allows you yo connect to any DNS server to perform administrator. This is why the option is grayed out. The idea of the video was to show how to create secondary zones and lookup zones, so don't worry to much about where the zones were created.

Very very helpfull & easy to understand, Thanks a ton.

Configure the DNS server to forward requests to the ISP DNS server. Add both servers to the forwarding list. The DNS server will use all the entries listed.

You only need the one. The second one is there is case the first DNS server is not available. If you have a look at our web site, link in the description, there is 4 videos on DNS in the 70-642 course.

Can't wait to have them :) , especially the examination part. Thanks again

Thanks, glad you like the videos. Any DNS address end in .local is not resolvable on the internet. The idea being that you don't want any of your clients on your network to be contacted directly on the internet. This can cause problems as the user may get confused with their computer ending in .local and their e-mail ending in .com

Is DC1 a global catalog server? Exchange requires global catalogs in order to run correctly.To run Exchange you should have a Global Catalog that is on the local network to the clients.

Thanks for the comment and I have added the website to the description of the video.

@jessicanldutch Proabably best to start with the Windows 7 course. On are channel we have a play list of all the videos in the order that they should be watched in.

Thanks for, sub, view and comment and thanks for watching.

Thanks very much.

Split brain DNS is when your external and internal address are the same, for example all end in .com. The problem is, you don't want your clients registering their computer names in a DNS server that is contacted on the internet. Thus what you do is you have public and private DNS servers. They essentially have the same zone, however local traffic is directed to the private DNS server and public traffic traffic to the Public DNS. This way clients are not registering records on the public DNS.

Thanks man ur a life saver :) .. Really appreciate info.

great vide.thanks alot guys, i really appreciate ur effort in providing us with this great tutorials

I have a question, if someone asks us- how many zones are there in DNS and what are those? Shall we explain which you have explained in this video or we should tell them about forward lookup zone & reverse lookup zone?

All the video's are so intresting. I might wanna study more:). But dunno where to begin

Old but gold

What do you mean? Do you have multiple dns server? If you have multiple clients it is a matter of having the a record for each client in the DNS server.

great video , thanks a lot

I find using primary zone and then primary server in a similar context confusing. Can a primary zone extend to move than one server and if so are all those servers considered primary?

Very helpfull video thank you very much.

great lecture. thanks a lot I don't know who disliked it and why ? please mention reason of disliking ?

Thank you very much for .i got it.

i have a little bit confuse about the differernce between forwarding and stub zone. stub zone forward the request to the main dns server and forwarding also forward the request . so why do we need to configure stub zone, if there is forwardin option??

Very good video

Lets say you forward all your DNS requests to your ISP which you can't add or modify records for. You later on need to do some work with anther company which means adding an external forest to your forest. The external company has it's own DNS which they have control over. So you want normal requests to go to ISP DNS and you want external forest requests to go to the other companies DNS. So you forward DNS to the ISP and create a Stub zone for the other forest. Problem solved.

Please refer to are web site for all are videos including this one. I have added the web address to the description. Please also indicate where you have seen this video before. This person has broke are copyright and we will be pushing legal action against as we are the copyright holder for this video. You help in this matter is appreciated.

very very helpfull ... thanks

How can i place my domain dns data in forestdnszones or domaindnszones ?.what the difference in forestdnszones and domaindnszones.

.The domain controller dc1 is the primary zone for the dns server which is not installed in domain controller .so,after trying to connect dns server the last option is grayed out because it is not a installed on dc .confusion ??? And u have created secondary zone forward lookup but not reverse .but u created reverse lookup in primary zone why ???......thanxs in advance

These days it is incorrect that a primary zone can only exists on one server. The thing is that the Active Directory integrated zone is by definition both a primary and secondary zone. The primary/secondary zone definitions come from BIND. However these days there are multiple DNS servers that use a database backend. Database here can be a SQL database. LDAP/ADDS or even some other structure. But every DNS server that can make updates to a zone is considered a primary DNS server for that zone..

No problem at all, thanks for watching.
